Abstract: A cutting tool comprising a cutting tool holder and a cutting insert adapted to be mounted thereon. The tool holder comprises an insert seat defined by a base and at least one side wall extending from the base to define an insert seat space adapted to receive therein the insert. The seat comprises a support element extending into the insert seat from the base, and a fastening member engageable with the seat. The fastening member is displaceable with respect thereto between a mounting position adapted to allow the insert to be mounted onto the seat and a securing position adapted for securing the insert within the seat. The insert is formed with a securing cavity and when the insert is mounted onto the tool holder and is in the securing position, a portion of the support element and the fastening member is received within the cavity of the insert.

Abstract: A cutting insert (20) comprising a cutting portion and a cooling portion. The cutting portion has a rake surface (26), a relief surface (28) and a cutting edge (24) defined at the intersection between the rake surface (26) and the relief surface (28). The cooling portion has an operative surface and a cooling nozzle (32) integrally formed therewith. The nozzle (32) is spaced from the cutting edge (24) and having a cooling aperture (CA2) directed at the cutting edge (24) at an acute angle with respect to the rake surface face (26). The operative surface is one of the rake surface (26) and a surface of the cutting element other than the rake surface (26), disposed at a location more remote from the cutting edge (24) than the rake surface (26), so that the rake surface (26) is disposed between the cutting edge (24) and the cooling aperture (CA2).

Abstract: A cutting tool holder adapted for mounting thereon a cutting insert having a top face, a bottom face and formed with an insert bore having an inner surface extending between the top and the bottom face. The holder comprises a seat defined by a bottom surface and at least one side wall angled to the bottom surface, a seat bore with a bore axis having an open end at the bottom surface of the seat, and a securing mechanism for securing the cutting insert in the seat. The securing mechanism comprises a securing pin received within the seat bore and having a body with an outer surface extending between a proximal end and a distal end of the body and defining a pin axis therealong.

Abstract: A cutting tool holder adapted for mounting thereon a cutting insert to form a cutting tool. The cutting tool holder comprises an insert seat defined by a base and at least one side wall extending from the base to define an insert seat space adapted for receiving the cutting insert. The cutting tool holder further comprises a support element extending into the insert seat from the base. The support element is (i) integrally formed with the insert seat or (ii) at least during operation, fixedly attached to the insert seat. The support element is formed with an undercut surface extending, at least during operation, at an acute angle to the base and away from the side wall. The insert seat is formed with a bore configured for receiving a fastening member for engagement with the insert seat.
